plate is mounted on studs 5, secured to the frame and having springs 6, which bear against the upper surface of the plate and .hold it to the frame with a yielding pressure whereby the plate will yield to permit the flange of the cover to pass thereunder. EX-

tending back from the plate 4 of the rece ta- 1 cle are two rails 7,-between which .wor s a slide plate or plunger 8, having an angular cut-away inner edge 9 and. havin a slot 10, in which is adjustably fixed a bloc 1 1, carrying a pin 12, to which is pivoted one end of an arm 13, having its other end pivoted to a lever 14. fixed to a vertical shaft 15, j o'urna'led in the framework. To shaft 15is fixed a curved lever 16, having its free end extending into the line of travel of a roller 17, loosely and eccentrically mounted on large gear-wheel 18,

.mounted on a shaft 19, journaled in the frame. Adapted to also make contact with roller 17 forthe purpose of returning shaft 15 after actuation through lever 16 is a short lever 20, fixed to shaft 15. The large gearwheel 18 is in mesh with a gear-wheel 21,fixed on a main driving-shaft 22, which is provided with a main driving-pulley 23, whereby the machine is driven from any suitable source of driving power.

The extension. 2 leads to a central rotating table 24-, fixed, on a central vertical shaft 25. The table is provided with an upper deck 26, forming a cover-carrier, which may be of con tinuous or solid construction or may be di- -vided into separate carrier-sections, each ada ted to receive and support a cover. The shaft 25 is adapted to be intermittently ro-' tated by a Geneva sto -movement con1pris ing a slotted star-whee 27, fixed on shaft 25, the pin 28 on an arm 29, carried by shaft 19, and mutilated guide-disk 30, also carried by shaft 19 and adapted to engage the arc-shaped portions of the star-wheel between the slotted extensions thereof.

Mounted in the deck 26, so as to slide radially therein above the table 24, is a series of pairs of slide bars 31, each bar of each air carrying a loosely-mounted roller 32. he

The lever 14 at its opposite end is slides 31 of each pair are joined by a crossarm 33, andan arm 34 extends from said cross-arm at right angles thereto and is connected to the deck 26 by a coiled return-- spring 35, which tends to keep the rollers 32 in against the deck, the edge of which has cut-out curved recesses 36 to receive the rollers; Opposite the midway point between the-rollers 32 and so..as to cooperate with both. is a smaller roller 37, having a milled vertical edge. Above said roller 37 and fixed to the deck 26 is a can-cover guide-plate 38.

Each of the milled rollers 37 1s fixed on the lfipper end of a vertically slidable and rotatae shaft 39, journaled in a bracket 40, de-

. pending from the under face of the table 24.

betweenthis collar and the bracket 40 is confined a coiled spring 42, the force of which is exerted to thrust u ward the shaft and the .roller 37. On the ower end of shaft 39 is fixed a roller or pulley 43. The upper projecting face of each of the rollers 43 travelsunder a shaft raising and lowering member consisting of a cam-rail 44 in the form of a ring surrounding the central vertical shaft 25. This ring is provided with, a cam part 45,

whereby the roller 43 and shaft 39 are forced downward tocarry down the milled roller 37 to withdraw it from clam ing position. The ring is also provided with a spring-pressed hinged section 46, adapted to be swung in to break the-continuity of the rail in order to permit the sudden and quick release of the roller 43 from the cam part and the. quick upward thrust of roller 37. Adapted to actuate an arm 47, carried by the hinged section 46, so as to operate said section, is a short lever 48, fixed on the oscillating shaft 15. The rollers or pulleys 43 in their circular travel are ada ted to be carried into dri-vin contact wit a belt 49, running horizontafiyacross .the machine-and tangentially to the circle of travel of the rollers or ulleys,'and carried on and driven by a puley 50, fixed on main 7 ';shaft 22, and on pulley 51, fixed on idle shaft 52, ournaled in the frame.

Mounted on the framework-1 is a compo- -sition-applyingmechanism. This mechan ism comprises a tank 53, adapted to contain the lining com ound and provided with a rotary stirrer or asher 54, which may be of any ordinary construction, and is shown in Fig. 4

' and is driven by belt 55, running over idle he shaft is provided with a collar 41, and.

box has a depending conical point 63, having an opening controlled by a needle-valve 64,

carried by a vertical rod 65, movable in a 9 frame 66, secured to the valve-box; Between a collar 67, fixed on the valve-rod, and the top of the valve-box, is confined a spring 68, which tends to force the valve-rod u wardly.

Ablock 69 is secured to the valve-r0 and has a pin 70 projecting therefrom. The pln 1s 7 adapted to be enga ed by a hook 71.0f al'ever 72, pivoted on the 1 ame 66 and'having con- L nected thereto a coiled spring 73, which tends to pull the lever downward and to hold ,the'

hook of the latter over, the pin 70. The lower arm of the lever 72 is adapted to bear'against' a pin 74, fixed on a block-75, secured to a vertically-slidin I dapted to make contact with and be raised by the can-cover as the latter passes under the same. a The pipe 60 rests upon a roller 7 7', carried by a crank-arm 7 8, fixed on the arm of a horizontal shaft 79, journaled in rod 76. The lower extremity the frame and having at its opposite end an-' I other crank 80,'pivoted to a hnk 81,which is pivotally connected at'its opposite end to a crank-arm fixed on the end of a rocklng shaft 83, provided with an arm 84, carrying on its end aroller 85, adaptted to bear upon a cam '19 is an upright post 87, havinga horizontal'arm screw or other projection above the vertical sliding rod 65;

The cover to be linedis designated by 89,

Fig. 13, and it has on its under surface a groove 90, formed b an upturned flange on the'ed e of which t 'e lining composition 1s alpplie and a groove 91, forming a head on. 13

Fixed on shaft 79 '88 extending therefrom, which arm has ae upper face of the cover, as, indicated in Figs. 13 and 14, thecover in said figures being shown-with the under surface uppermoit. 1 e on t e.

Extending along a portion of the ta frame is a guard-rail 92. An inclined stopbar 93 extends acrossthe carrier and is fixed to an arm 94. Opposite the stop-bar is a chute 95, into which the line'dcovers are thrown by-the stop-bar asthey are carried The operation 0 The machine is driven throughpulley 23 on main shaft 22, which infturn by gear 21 drives wheel 18 and-shaft 19. will be intermittently rotated by the Geneva stop-movement and at' each actuation will rotate the table '24 and carry a cover-receiving f the machine is as follows The central shaft 25.

section of the deck or carrier 26 and a set of i clamping-rollers 32 32 37 opposite the feed-'1 receptacle 3 4, where the earner will stop un--'- til a cover has been fed thereon by the feed- I As the carrieris stopped opposite the feed 'mechanismithe roller 17, eccentrically mounted on gear-wheel 18, will'strike against leve'r16, fixedon shaft 15, and turn said shaft, so as to carry'inwardlythelever 14 and arm 13' and slide the pliin'ge'ror feedslide 8 inwardly, whereby a single cover will be fed from the receptacle 3 under plate 4 and out upon the carrier. The plate 4 is held above the extension 2 a heightjust sufficient to permit a single cover at a time to pass down through the aperture in the plate 4 and rest upon the extension. -As the cover is forced under the plate 4 the latter will yield upwardly on the springcarryingstuds 5, so, as to permit the beads of the cover to pass thereunder. The cover 89, which is shownwith the under side uppermost in Figs. 13 and 14, is carried to the carrier under a guiding spring-tongue 94, extending from plate 4 over the carrier. The plunger forces the cover against the roller 32, and thus slides said rollers inward against the pull of spring 35 until the bead or groove 91. of the cover 89 has passed beyond the periphery of the milled roller 37, whereupon in the continued action of the driving means said milled roller 31 will be automatically thrust upward by the vertical upward movement of its shaft 39 whose fixed roller or pulley 43 will be released from the cam-ring 44 by the pivotal swing of the hinged section 46 away from said roller or pulley by the actuation of lever 48 contacting with cam 47 when rocked by shaft 15. When the roller 37 is in its upward position, the cam-co er head will be firmly clamped between the milled edge of said roller and the spring-pressed clamping-rollers 32. At the next rotation of the table and covercarrier by the intermittently-acting Geneva movement the cover will be carried tothe composition-applying mechanism, while another carrier receiving section will be positioned in front of the feed mechanism and another cover fed to the carrier. As the first cover is carried under the eomposition-applying mechanism the controlling-valve box 62 is lowered. by the action of cam 86 on shaft 19 through. cranks 84 82 and shaft 83, so that the conical open point 63 will enter the groove 90 of cover 89, whercu pon the surface of the body of the cover will ride under and bear against the vertically-sliding rod 76, so as to raise said rod and the pin 74. This movement will rock thei'lever 72 on its pivot and release the hook 71 from the pin 70 of the valve rod 65, whereby the valve-rod is permitted to be forced upwardly by spring 63. When the rod moves up, it carries the valve 64 away from the opening in the conical point 63 and permits the composition to flow out into the groove of the cover. The composition is agitated in the tank 53 by the dasher and is forced out freely through the exit-pipe and valve-box by the admission of compressed air. Simultaneously with the positioning of the cover under the composition mechanism the cover is given a rotary movement under the conical end of the valvebox, so as to line the groove with the composition. This movement is effected by the contact of roller 43 on the lower end of the shafts 39 with the continuously-driven.belt 49, whereby the covers tightly gripped'between the rollers 32 and 37 are carried around under the valve-box several times, whereby the lining is thoroughly applied. As the cover leaves the composition-applying mech anism the latter is again raised above the clamping-rollers by the cam 86, and the upper endof valve-rod 65 will strike against the bar 88 and the valve-rod and valve will be forced down'relatively to the valve-box until the pin catches under the hook 7]. of the spring-pressed levcr72, whereby the opening of the valve-box will be closed and the escape of the lining composition stopped. Should the carrier be driven past the compositionapplying mechanism without carrying a cover thereon, themechanism'would not be operated, since the rod 76 will not with the carrier, but will be lit ted onlyby the contact of the cover. After the coverpasses' the lining mechanism the roller 43 on the clamp-roll shalt will ride on cam 45 or rail 44, and the clamp-roll 37 will be pulled-down out of engagement with the cover, and the rollers 32 will be thrown outward again. The guard-rail 92 prevents the cover from being thrown oil the carrier until the cover strikes the inclined stop-arm 93, whereby it will be thrown oil into the chute 95, from whence it may be carried by anysuitable means, if desired, to a drying device.

In the m achine herein set forth I have shown a gang of six clamping devices; but it is clear that a greater or less number may be em ployed and also that various other changes in the details of the machine may be made without departing from the principle of my invention.

Having thus described my invention, what I claim is i 1.
